+# NixOS Manual {#book-nixos-manual}
+## Version @NIXOS_VERSION@
+
+<!--
+  this is the top-level structure file for the nixos manual.
+
+  the manual structure extends the nixpkgs commonmark further with include
+  blocks to allow better organization of input text. there are six types of
+  include blocks: preface, parts, chapters, sections, appendix, and options.
+  each type except `options`` corresponds to the docbook elements of (roughly)
+  the same name, and can itself can further include blocks to denote its
+  substructure.
+
+  non-`options`` include blocks are fenced code blocks that list a number of
+  files to include, in the form
+
+     ```{=include=} <type>
+     <file-name-1>
+     <file-name-2>
+     <...>
+     ```
+
+  `options` include blocks do not list file names but contain a list of key-value
+  pairs that describe the options to be included and how to convert them into
+  elements of the manual output type:
+
+      ```{=include=} options
+      id-prefix: <options id prefix>
+      list-id: <variable list element id>
+      source: <path to options.json>

+# Preface {#preface}
+
+This manual describes how to install, use and extend NixOS, a Linux distribution based on the purely functional package management system [Nix](https://nixos.org/nix), that is composed using modules and packages defined in the [Nixpkgs](https://nixos.org/nixpkgs) project.
+
+Additional information regarding the Nix package manager and the Nixpkgs project can be found in respectively the [Nix manual](https://nixos.org/nix/manual) and the [Nixpkgs manual](https://nixos.org/nixpkgs/manual).
+
+If you encounter problems, please report them on the [`Discourse`](https://discourse.nixos.org), the [Matrix room](https://matrix.to/#nix:nixos.org), or on the [`#nixos` channel on Libera.Chat](irc://irc.libera.chat/#nixos). Alternatively, consider [contributing to this manual](#chap-contributing). Bugs should be reported in [NixOS’ GitHub issue tracker](https://github.com/NixOS/nixpkgs/issues).
+
+::: {.note}
+Commands prefixed with `#` have to be run as root, either requiring to login as root user or temporarily switching to it using `sudo` for example.
